Abstract: In recent years, a new generation 600km/h normal-conducting high-speed maglev engineering prototype vehicle has been developed inChina.oweueteckofodstaeeggtstlitetichigspdaglevprtotstdgoea ful-speedtestiisytdctoongcodatiooualaoAtti thethreshold of track irregularity at the speed of 600kmh is also unclear.To address the above issues, this paper jointly uses UM,ANsYS and Simulinksoftwaretobuildaighspeedmaglevvehicle-magne-trackcouplingdyamicssimuationmodelandverifiesthemodelusing measureddataoeagie.Usingisodel,witteiputofangailietckegityxciatio,tedacssof thehigh-speed maglev vehicle subsystem,suspension subsystem,and track beam subsystem at 600km/h are analyzed.On this basis,the threshold of track irregularity at the speed of 600km/h is explored based on dynamic calculations.
